T 0 all whom it may concern:

Be it known that I, Nrnrrnmr F. D. GRENINGER, citizen of the United States, residing at Bridgeport, in the county of Fair field and State of Connecticut, have invented certain new and useful Improvements in Metal Tubular Shade Rollers and I do hereby declare the following to be a full, clear,

and exact description of the invention, such as will enable others skilled in the art to which it 'appertains to make 'and use the same.

My invention relates to metal tubular shade rollers, and it consists in certain novel details of construction to be more fully set forth in the following specification.-

Referring to the accompanying drawings wherein the same figures of reference indicate like parts throughout the several views,

Figure 1 represents the roller, shade and bracket construction;

Figure 2 is an enlarged detail view of the metal tubular roller;

Figure 3 is an enlarged detail inside elevation of the shade clamp;

Figure 4 is an enlarged detail end elevation of the roller; i

Figure 5 is an enlarged detail end elevation of the shade clamp and broken section of the shade;

Figure 6 is an enlarged end elevation of the roller, showing the shade clampengag'ed therewith minus the shade;

Figure 7 is an enlarged detail end elevation of the outside of the shade clamp locking plate; f Figure 8 is an enlarged broken view of roller, shade clamp, locking plate, and brokon View of the central rod;

Figure 9 is an enlarged detail outside elevation of one of the end locking plates, and

Figure 10 is an enlarged broken end elevation of the roller, shade clamp and broken view of the interlocked shade.

The roller proper comprises the metaltube 1 havingthe opposed indentations 2, Figures 2 and 4:, formedin each end thereof. 3 is a semi-circular clamp the length of the roller and partially embracing the tubular roller. The short'eyes l are formed at each end to receive the locating pins '5, Figure 3.

6, Figures 3 and 5, is a metal binding. strip extending the full length of the clamp H inner cylindrical surface of the clamp 3 and the binding strip 6, Figure 5. In assembling the fixture, the end of the shade is inserted within the clamp 3 as previously mentioned, and the clamp closed upon the roller 1, with the eyes 4: inserted into thedepressions 2 and are held therein by theendlocking plates 8 provided with the holes 9 for the reception of the pins 5. The plates have the central openings 10 for the reception of the rod 11 whose outer ends form bearings adapted to be j'ournaled in the end brackets 12, Figure 1. 13are lugs on the inside face of the locking plates adapted to engage the inside surface of the roller to centralize the rod 11 with respect to theroller. plates 8 will lock the entire construction together in operative position, and when journaled in the end brackets, the several elements cannot become accidently displaced.

The usual mechanism for winding the shade and temporarily holding it in any adjusted position is not shown, as such mechanism is well known and, therefore, formsnopart of the present invention. Any suitable end brackets for supporting the ends of the central rod may be used. I I As an additional means forgrippingthe shade firmly to the roller it is forced into one of the depressions in the tubular roller by one of the eyes 4, asit is delivered from between the strip .6 and the clamp 3, as shown in Fi re 10. g

, Having thus described my invention what I claim is When thus assembled, the

1. A tubular metal shade roller having oppositely located depressions in its outer surface and in each end thereof, a semi-circular metal shade clamp partially embracingthe roller and having oppositely! located eyes formed in each end and in the edges thereof adapted to be seatedin the depressions of the roller, a metal binding strip for the shade, said shade projecting therefrom and further anchored by one of the eyes of the clamp to the roller, a rod passing through the roller, end supports therefor, and means for centralizing the roller with the rod. 7 v

2. A tubular metal shade roller having oppositely located depressions in its outer surface and in each end thereof, a semicircular metal clamp partially embracing the roller and having oppositely located eyes formed in each end and in the edges thereof adapted to be seated in thedepressions of the roller, a metal binding strip for the inner end of the shade, said shade projecting therefrom and further anchored by one of the eyes of the clamp to the roller, a rod extending through the roller, brackets in which the projecting ends of the rod are journaled pins located in the eyes of the clamp and projecting outwardly therefrom,

end plates mounted on the rod having openlllgS thereln to receive said pins and lock the clamp to theroller, said plates having circumferentially arranged lugs on their inner faces adapted to engage the inner surface of the roller to centralize the rod with respect to the roller.

In testimony whereof I afiix my signature.

WILHELM F. D. GRENINGER.
